Wyoming Department of Environmental Quality (DEQ) Solid and Hazardous Waste Division
Comparison: State vs. Federal
· Rules. Wyoming incorporates by reference the federal hazardous waste storage rules, including those for on-site storage by generators, and adds a notification requirement for hazardous waste small quantity generators (SQGs).
· Administration and enforcement. The DEQ administers and enforces the hazardous waste storage regulations in Wyoming.
The federal rules require SQGs to immediately notify the National Response Center (using their 24-hour toll free number 800/424-8802) in the event of a fire, explosion, or other release which could threaten human health outside the facility, or when the generator has knowledge that a spill has reached surface water. In addition, Wyoming requires an SQG’s emergency coordinator to immediately notify DEQ at its 24-hour telephone number: 307-777-7781.
